Hi Jacob,
Getting no responses whatsoever has nothing to do with your looks. There are many people of varying looks that have been able to meet partners on dating sites.
Yes, it all starts with your bio and profile pics.
Your bio has to be appealing and your profile pics have to be well-taken. It all starts with your overall impression. What impression do you want to send to whoever views your dating profile?
It could have something to do with your personality, lifestyle, way of thinking, aspirations, etc. Use that as a theme and now construct your bio and profile pics around that theme.
People are a lot more likely to respond to your dating profile when they get a clear understanding of the impression that you are conveying, than if it feels like your bio is all over the place and chaotic.
